Abstract

a presente invenção refere-se a um processo para produção de pelotas a partir de copolímeros de olefinas. o processo compreende: (i) fusão de copolímero de olefina em um extrusor; (ii) extrusão de copolímero de olefina fundido através de uma placa de cossinete em um banho de água de pelota em um peletizador pelo que produzindo tiras do copolímero de olefina; (iii) corte de tiras do copolímero de olefina no peletizador em pelotas; e (iv) secagem de pelotas. a água de pelota no peletizador contém de 0,1 a 5% em peso de uma sílica coloidal baseado no peso da água.
